Yeah I just tried it out--and the userface for the webtoon crop is really simple and nice. Only problem is that it is...saved through Clip Studio's compression engine, so my files were too big. I had to go back and re-save them in Photoshop anyway to get my files from 23.4 mb to 16.3 mb. So...it definately works! And so long as you aren't a crazy person like me cramming 2 big episodes into one episode for Webtoon, it saves a ton of time.
